Environmental Data Viewer
This application allows you to interact with the WECC environmental risk classes
within the Western Interconnect region. Click on a location to see its
risk class and area types (last update 12/2017).
You can also sketch or upload a proposed corridor and report the risk classes, area types, terrain, and land cover that are crossed by the line.
You will receive instant analytics, capital and mitigation cost estimates, and the options of downloading tabular data
and your line geometry as a Google Earth KML file.
Use the tools on the right side of your screen to control and interact with the map.
The data presented is intended for use in WECC’s 10- and 20-year Transmission Expansion Plans,
as well as by other organizations in their early stage transmission corridor planning efforts.
Because of the scale at which the regional Transmission Expansion Planning process operates,
it is not possible to consider all project-level data that could be critical during transmission line siting.
WECC recommends any potential transmission corridors generated through this mapping application be thoroughly reviewed
against siting-level data and any applicable laws and regulations.
Drawing a few sample lines is recommended to get acquainted with the Corridor Mapping tools.
Click on the map to begin. Each subsequent click will place a new vertex. To complete the line,
simply click on the final point after it is placed. Avoid rapid double-clicking, as this may cause
errors.
[Undo] will remove the most recent vertex.
[Cancel] will remove the line you are currently drawing.
Editing allows you to add and move vertices.
[Save] will commit any changes permanently
[Cancel] will remove vertices added in the editing process, but will not revert
the movement of original vertices moved in the editing process.
After clicking the Delete button, click on any drawn line to remove it from the map.
[Save] will permanently remove all lines selected in the deletion process.
[Cancel] will return all lines selected for deletion
All drawn lines exist only in the current browser session and is not saved.
